higher expression of STXBP5, GALP and LOC387646 indicated poor prognosis for a breast cancer patientincreased CTSLP8 and RPS10P20 and decreased HLA-K pseudogene expression indicates poor prognosis; regarding pseudogene–gene interaction, GPS2-GPS2P1 improved prognosis, but neither the gene nor pseudogene alone is prognostic of survivalmiR-3923 was predicted to target GPS2 using miRanda, PicTar, and TargetScan, implying modules of gene–pseudogene miRNAs that are potentially functionally related to patient survival. This evidence concerns the gene GPS2 and breast cancer.
